The first night in a hotel costs 40 dollars. All additional nights cost 27 dollars. How many nights did we stay
at this hotel if the total bill was 148 dollars?

Answers

Answer:

Step-by-step explanation:

First, you would want to subtract the first nights cost from the bill, which you would get 108. And then you would want to divide 108 by how much it costs to stay additional night, so 108 divided by 27 = 4. But you have to remember to add the first night you stayed so it would be 5. I hope this helps :)

Answer:

4 nights

Step-by-step explanation:

148-40=108

108÷27=4

So, you spent 4 nights at the hotel.

Answers

Answer:

a = 6

Step-by-step explanation:

120 = 3 + 3(7a - 3) (by PEDMAS, expand parentheses first by distributive property)

120 = 3 + 7a(3) - 3(3)

120 = 3 + 21a - 9

120 = 21a - 6 (add 6 to both sides and rearrange)

21a = 120 + 6

21a = 126 (divide both sides by 21)

a = 126/21

a = 6

Step-by-step explanation:

120-(3+3*(7*a-3))=0

Step by step solution :

STEP

Equation at the end of step 1

120 - (3 + 3 • (7a - 3)) = 0

STEP

Pulling out like terms :

3.1 Pull out like factors :

126 - 21a = -21 • (a - 6)

Equation at the end of step

-21 • (a - 6) = 0

STEP

Equations which are never true:

4.1 Solve : -21 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2 Solve : a-6 = 0

Add 6 to both sides of the equation :

a = 6

One solution was found :

a = 6

)Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:

Year Lawn Care Fee
2000 $750
2010 $1350

A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.

Answers

Answer:

Rate of change = (1350 - 750)/(2010 - 2000) = 600/10 = $60

Initial value = $750

Equation is y = 60x + 750; where y is the amount charged to customer and x is the number of years from 2000.

Answers

Answer:

x=-7

Step-by-step explanation:

-2(x−3)+4x=−(−x+1)

Step 1: Simplify both sides of the equation.

−2(x−3)+4x=−(−x+1)

−2)(x)+(−2)(−3)+4x=x+−1(Distribute)

−2x+6+4x=x+−1

(−2x+4x)+(6)=x−1(Combine Like Terms)

2x+6=x−1

Step 2: Subtract x from both sides.

2x+6−x=x−1−x

x+6=−1

Step 3: Subtract 6 from both sides.

x+6−6=−1−6

Jake lives 2⅓mile from school. He decides to walk to the shop on his way home. The shop is 1⅜mile from school. A) What is the shortest possible distance from the shop to his home? B) What is the largest possible distance from the shop to his home?

Answers

Answer:

Shortest distance = 23/24

Farthest distance = 3 17/24 miles

Step-by-step explanation:

Distance of home from school = 2 1/3 miles

Distance of shop from school = 1 3/8 miles

Shortest distance possible :

(2 1/3 - 1 3/8) miles

(7/3 - 11/8) miles

L. C. M = 24

(56 - 33) / 24

23 / 24 miles

The farthest distance :

(2 1/3 + 1 3/8) miles

(7/3 + 11/8) miles

L. C. M = 24

(56 + 33) / 24

89 / 24

= 3 17/24 miles
